I am studying imaging, want to take a license, how so difficult?

Engaged in medical imaging, divided into two lines, one is engaged in pure medical imaging technology, that is, the technician line, such as radiographers, CT technologists, etc., do not need to take a licensed physician's license, relatively easy to obtain and promotion, but no right to issue diagnostic reports. The other line is medical imaging diagnosis, i.e. physician line, such as radiologist, CT or MR physician, requires a licensed physician's license, and larger hospitals also require a large medical equipment induction certificate, with the right to issue diagnostic imaging reports, promotion is relatively difficult, but there is a sense of achievement and honor. Want to test the appropriate certificate, according to their own learning and professional knowledge and skill level, and then break the boat, picking the lights to read at night, will certainly be able to successfully pass. Good luck!
